%% Plot Response of a Crossed-Dipole Antenna % Examine the response patterns of a crossed-dipole antenna used in an L-band % radar with a frequency range between 1-2 GHz. % Copyright 2015 The MathWorks, Inc. %% % First, set up the radar parameters, and obtain the vertical and horizontal % polarization responses at five different directions: elevation angles -30, -15, 0, % 15 and 30 degrees, all at 0 degrees azimuth angle. The responses are computed % at an operating frequency of 1.5 GHz. sCD = phased.CrossedDipoleAntennaElement(...
